ROTARY MOTOR.

Specification of Letters Patent.

Patented Oct. 24:, 1911.

Application filed. February 27, 1911. Serial No. 610,984.

To all whom it may concern:

Be it known that I, JAMEs MAOKEY, a citizen of the United States, and a resident of Steamboat Springs, in the county of Routt, State of Colorado, have invented a new and useful Improvement in Rotary Motors, of which the following is a specification.

My invention is an improvement in rotary motors, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof: Figure 1 is a section on the line l-1 of Fig. 2; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a-perspective view of the rotor; Fig. 4: is an edge view of a modified form; Fig. 5 is a face view of Fig. 4; Fig. 6 is a section on the line 66 of Fig. 5; and Fig. 7 is a partial face view of a rotor showing another modification.

The present embodiment of the invention comprises a standard 1 having a foot 2 by means of which it may be held to a support, and a bearing 3 in which is held the hub 4 of a disk 5 forming a part of the motor casing to be described, by means of a set-screw 6. The set-screw is threaded through an opening in the bearing and engages a recess in the hub.

A pipe or hollow shaft 7 is journaled in the hub, and a pulley 8 is secured to the shaft on the opposite side of the hearing from the disk 5. An inlet pipe 9 fits into the outer end of the hollow shaft and is held by a packing nut 10 threaded into the shaft.

The casing is completed by a ring 11 held co-axial with the disk by cap screws 12, and a supplementary or auxiliary casing 13 having an annular flange 14 connected to the ring by cap screws 15. The casing 13 is cylindrical in form and 1s open toward the disk 5 and is provided with a hub 16 in which is received the shaft 7 The auxiliary casing is provided with an.

26 connects the inner end of the rod with the valve 18. The hub 16 of the casing is provided with an inclined oil passage 27 leading. from the outer face of casing to the periphery of the shaft and a pin 28 is passed through the rod 24 at the inner end of the sleeve.

The rotor comprises a disk 30 and a cover 29 held to the disk by cap screws 32. The disk 30 is provided with a plurality of series of discharge passages 31 and 31 The passages 31, Fig. 2, extend from the center of the disk parallel with a diameter of the disk to a point near the periphery of the disk Where they bend laterally toward the periphcry of the disk and discharge tangentially to the inner face of the ring 11.

The passages 3-1 extend in the same manner, but in the opposite direction. A bushing 33 encircles the shaft 7, and the cover 29 is provided with a central opening for receiving the bushing, and the bushing is provided with a radialflange 34: at its inner end abutting against the inner face of the cover.

The shaft 7 is provided with two annular series of openings 36 and 39, and the valve 18 when moved in the sleeve will open one series and close the other. The passages 31 and 31 are arranged alternately, and the passages 31 communicate with the openings 36, while the passages 31 communicate with the passages 39. The web of the disk 30 is provided with transverse passages 40 which permit the exhaust fluid to escape into the auxiliary casing 13.

It will be evident that when the motive fluid is admitted to the hollow shaft the said fluid will pass through the openings 36 and 39, depending upon the position of the valve 10, and will rotate the rotor in either direction, in accordance with the position of the valve. The inner surface of the ring 11 is provided with transverse notches 41, forming blades or vanes 38, against which the motive fluid impinges as it leaves the pas-- sages.

In operation, the valve 18 being in the position shown in Fig. 1, the motive fluid passes through the passages 31 and rotates the valve in the forward direction. When it is desired to reverse the rotor the valve 18 is moved to the right of Fig. 1, covering the passages 36 and uncovering the passages 39, so that the fluid passes through the openings 19, thus reversing the direction of rotation of the valve. The exhaust fluid (Fig. 3)

passes from the blades or vanes through openings 12 between the passages 31 and 31 into chambers 43 in the disk, and from the chambers through the openings 40 into the auxiliary casing 13 and through the exhaust pipe 19 to the atmosphere.

In Figs. 4c, 5 and 6 the hollow shaft 44: is provided with but one series of openings 15 and the rotor, comprising a disk 16 and a cover 47, is providedwith but one series of passages 48. The casing 16 is provided with blades or vanes 50, and the rotor is also provided with blades or vanes 51 in front of the outlet of each passage 48. A radial passage 52 is provided at the end of each series of blades 51, which opens into a chamber 53, and the disk has a transverse passage 54 for each chamber.

It will be noticed that the motor is provided with a passage 49 leading from the outlet or discharge end of each radial passage 48 to the passage 52, and that the said passages or ports 49 gradually increase in cross section from the said outlet or discharge end to the passages 52.

In the above mentioned construction no provision is made for reversing, so that the rotor moves in one direction. In Fig. 7 the blades 51 are omitted, the construction being otherwise the same. It will be noticed in Fig. 7 that a rib 55 is arranged on the face of the disk leading from the opening of the passage 56 to the chamber 57, and that the outer face of the rib inclines inwardly from the passage to the chamber. A passage or port 57 is thus provided leading from the discharge end of the radial passages to the chambers 57, and the said passages or ports 57 gradually increase in cross section from the outlet of the radial passage to the chamber. In Fig. 5 a similar rib 58 is provided which carries the blades 51. The said ribs are so arranged to permit the steam to expand.
